Title: Method and a circuit arrangement for signal processing in a telecommunication system
Inventor: OSTMAN KJELL
IPC: H04B1/18
Filed: 1997-02-28
Abstract: The object of the invention is a method and a circuit arrangement for processing a spread spectrum signal and a frequency modulated signal. According to the invention the radio frequency signal is received (1, 2), the received signal is converted into an intermediate frequency signal (3, 4a, 4b), and then an intermediate frequency signal processing (6, 30, 31, 40) is made and the processed intermediate frequency signals are converted (32, 42a, 42b) into baseband signals. The signal derived from the received signal is converted (41) into a digital sampled signal which is processed (32, 42a, 42b, 111, 120, 121) digitally, whereby the either a signal derived from the received spread spectrum signal or a signal derived from the received frequency modulated signal, respectively, is selected (5) as the signal which is converted to the digital sampled signal. According to the invention the same intermediate frequency and baseband components (6, 7, 30, 31, 40, 41) can be used to process both the spread spectrum signal and the frequency modulated signal.

Title: Method for controlling refrigerant based air conditioner leaving air temperature
Inventor: GROENEWOLD PETER E
IPC: F24F11/76
Filed: 1998-02-13
Abstract: Precise control of the temperatures of leaving air in an air conditioning system and of leaving water in a water heating system are obtained with a throttling valve whose flow rate is modulated with an electric signal. The high pressure outlet of a refrigerant compressor is coupled jointly to the inlet of the valve and to the refrigerant inlet of a first condenser and the outlet of the valve is coupled jointly to the refrigerant outlet of the first condenser and to the refrigerant inlet of a second condenser. A programmable controller receives input signals corresponding to one or more entering media characteristics, such as dry bulb temperature, dew point temperature, and percent humidity and produces control signals that modulate them valve flow rate to thereby maintain the leaving air or water temperature at a specified set point with high precision.

IPC: H01S3/06
Filed: 1996-12-20
Abstract: A monolithic solid state laser structure is used to construct erbium lasers that are insensitive to external pressure changes and vibrations, and have improved cooling of the gain medium (20) and reduced thermal lensing effect.  In the monolithic laser structure, the gain medium (20) is separated from an optically transmissive plate (24) on one side and a wave plate (21) on the other side by spacers to form narrow air gaps (31 and 33) which provide effective cooling of the gain medium (20) and reduced the thermal lensing effect. Such an arrangement is further combined with a pressure-insensitive brewster polarizer such as a solid brewster polarizer (42 and 46), or a pressure-sealed brewster plate (249), to form a pressure-insensitive laser cavity. The wave plate (2') cooperates with the brewster polarizer (42 and 46) to select the wavelength of the solid state laser.
